2.17.3 Audio power source setting (J7)

The PCM-9550F/FM is designed to work with a single +5 V power

supply. The audio interface can also function normally under

single +5V power supply, but most audio controllers require an

independent power source generated from a +12 V power supply.

The independent power source avoids the noise from the other

digital circuits. The PCM-9550F/FM’s audio interface can accept

+12 V power to provide improved quality audio. This is done via

J7.

*+5 V +12 V

* default setting

Configuration of the audio interface is done entirely via the

software utility. You do not have to set any jumpers. Refer to

Chapter 6 for audio setup details.
